I have a 90 accord lx/dx.I replaced fuel filter, air filter and now the car won't stay running and once it does start after running it about 2 blocks if you let off the accelerator it putters like it'sh out of gas then smoke starts comeing out of the air filter.after that it doesn't want to start but when it does it will idol until you put into drive than it putters like its out of gas.

Have your engine scoped out by a reputable service shop. Was it running better before you replaced those items? Have you done a tune up lately? Did you buy bad gas? Are your fuel injectors clean? Is the fuel pump going out on you? Are your spark plugs and spark plug wires good? Are their any sensors that may need replacing? I have a 1990 Honda Accord and the car just wants to keep taking my money. It needs too much love to keep any more.
